S A C HU S E T T S. Letters-Patent No. 83,362, dated .Ma/rolt 30, 1869.

` The Schedule referred to in these Letters Patent and making part of'the same. y

To all fcham tt may concern Be it known that we, JOHN A. BRADsHAw andWn,-y LIAM H. BROWN, both of Lowell, in the county of Middlesex, andState of Massachusetts, have invented new and useful Improvements inWater-Meters; and we do hereby declare that the following is a full andexact de- 'scrpton thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

The nature of our invention consists in providing a wateremetcrwithseveral devices, so arranged and constructed that the amount, orquantity of water used may Vbe accurately measnred,and at the same timebe selfv responding parts. c represents the pedestal, to which issecured firmly,

the stand b, the bottom of this stand being supplied with a flange, towhich is secured the meter-case b. The stand bis also provided with areceiving-pipe, c, whichconveys the water to and through the centre ofthe same, into the chamber c', where it then passes through the apertured into the meter-chamber d; this chamber, d', as represented in thedrawings, being of a triangular form, but may be made in various forms,as desired.

The disk-edge c, of the meter-chamber d', is finished true and levelwith the seat e', which is formed in the top of the meter-case 1X,- onthe outside 'of the meterchamber d',

f is the discharge-pipe, which connects with the meter-chamber d. Thischamber is further provided with which is located in the same, betweenthe even with the seat c and disk-edge c.

rlhe side of this foothold f, nearest the aperture cl, is lsupplied withelastic packing g, thel other side being provided with an inclinedplane, g.-

it is the float-plate, its under side being finished off true and level,which, when placed in position, will bear equally on the disk-edge e andseat c', thus forming a cover for the meter-chamber df, making itperfectly water-tight. rlhis float-plate 7L is provided with recesses71,', fl, and i', suitably packed with elastic packing j j j, and la',which correspond exactlyin shape with the metercharnber d'. They areprovided with elastic packing l l l, and hung in the under surface ofthe plate h, by suitable gndgeons, or shafts mf, n, and u', one bearingnear the centre of said plate, and the other near its periphery, andprojecting through the same, their ends being so constructed as to formarms o, o', and p.

' The iloats j, k, and t, when closed in the recesses h' 'i i', areilush with the under side of the plate h, their weight being suflicientto open thein when in position. They are kept Open by the semicircularprojection m, the leaves coming directly against the edge of therecesses h', t, and i', forming a perfect joint, water-tight, betweenthesame and plate h.

Passing-through the plate h, and secured to the same, is the shaft p',which is provided with bearings at each end; its lower bearing restingin the socket c',and adjusted by means of the screw q, the `top bearinglitting or working in the soeketj, and adjusted by the screw r, whichpasses through the top of the stand fr', which is secured on and to thecap s,by means of screws.

Attached to the extreme end of the shaft p is the pinion l', which, whenthe shaft p'iis in operation, iinparts motion to a worm, or gear, whichmay be attached to a suitable clock, which will indicate the workperformed, as desired,

The cap s, in its inside, is furnished with a semicircular projection,fm, its object being, when the floatplate his in motion, the arms o, o',and p, will operate 'on the surface of the same, keeping the doats j',k, and

lt open, as desired. The under side otthis cap s is turned,

and iinishedtrue, to correspond with the top and finish of themeter-case b', and when properly secured to thesanie, is water-tight.

The meter being thus constructed, and its several parts Jlinished, andadjusted in their respective plaes, and properly secured, is then readyfor use. Water is let into the receiving-pipe c, passing through thesame into and through the centre ofthe standluthence to thechamber c,forcing through the aperture d, into the meter-chamber d,'where it comesin contact with tlre floats j', lo, and la', one at a time, and footholdj', which being firm and stationary, and properly packed, the wholeforce and pressure of the water is thrown against the doats, carryingthe neat-platel lz, around until another float, It, receives the samepressure, and so on, float succeeding iioat alternately, as long as theplate h revolves. The water being carried ibrward, and prevented frompassing around the foothold j', is forced to escape, with greatpressure, through the discharge ipe fi p The floats j, lr, and lo', areclosed alternately before passing the foothold f, by the aid of theinclined plane g', their Weight, with the aid of the projection m,opening them, after passing the foothold j', and. they are kept open bythe assistance of the semicircular projection lm, until all the water inadvance of each lioat is dis charged through the discharge-pipe f.

The quantity of' water contained between the oat and foothold f,orone-third'of the contents of the chamber d', the measurement, orcalculation of' water discharged is easily and readily computed, by thenumber of revolutions of' the shaft p, which is indicated on the clockby the assistance of the pinion'i.

Thus it will be seen, that with our improved watermeter, we are enabledto accurately measure the water from any service-pipe that may berequired,simply by opening the discharge-pipe f, and force the same, asdesired, with this device, which is simple in its construction, cheap,'reliable, and durable.

What we claim as our invention, and desire to secure by Letters Patent',is

l. The combination of the meter-case b', foothold f', with packing g andinclined plane gf, when constructed and arranged to operate as hereindescribed, and for the purposes set forth.

2. In combination with the arms o, o,'andp, the

.7", 7c, and k', shaft y', adjustable screws q and fr, metercase b',with chamber d', foothold j, inclined plane g',

and discharge-pipe j; stand b, with receiving-pipo e, all

when constructed and arranged to operate substantially as and for thepurposes herein described and set forth.
